Title: Protective device for semiconductor laser
Inventor: ASANO MITSUGI
IPC: H01S5/042
Filed: 1983-02-10
Abstract: PURPOSE:To prevent the deterioration or breakdown of a semiconductor laser by bypassing currents flowing through the semiconductor laser when overcurrents flow through the semiconductor laser and an optical output from the semiconductor laser intends to exceed a fixed value. CONSTITUTION:When overcurrents intend to flow through a semiconductor laser 1, an optical output from the laser 1 increases. The impedance of a photodiode 2 drops at the same time, and input voltage to a minus terminal for a comparison amplifier 5 drops. When the input voltage drops to a value lower than the threshold voltage of the amplifier 5, an output from the amplifier reaches an ''H'' level, and an output from an AND circuit 7 is brought to an ''L'' level. An inverter 8 receives the signal of the ''L'' level, an output from the inverter is brought to an ''H'' level, and a thyristor 4 is turned ON. Consequently, most of currents flowing the laser 1 by that time are bypassed to the thyristor 4 side, and currents hardly flow through the laser 1. Accordingly, the laser 1 can be protected from breakdown or deterioration.

Title: Continuous casting method of steel
Inventor: UEJIMA YOSHIYUKI
IPC: B22D11/124
Filed: 1984-02-10
Abstract: PURPOSE:To prevent surface flawing, cracking, etc. of a steel having a specific carbon concn. in continuous casting of said steel by specifying the cooling rate in the stage of the peritectic reaction, Ar4 transformation or phase change of both during cooling at a specific value or below and avoiding the overlap segregation of harmful elements by a difference in taking-in of elements. CONSTITUTION:A molten steel L changes to a gamma phase from an L+delta phase via a delta phase, an Ar4 phase or L+gamma phase in continuous casting and cooling of a steel having 0.005-0.53wt% carbon concn. The cooling rate of the phase change region centering at 1,495 deg.C (line 3) of the phase change is specified at <=40 deg.C/min so that the alpha stabilizing elements easily meltable in the delta phase (P, Si, S, Cr, Nb, V, Mo, etc.) and the gamma stabilizing elements easily meltable in the gamma phase (C, Mn, Ni, etc.) are thoroughly absorbed dividedly to the delta phas and the gamma phase. The overlap segregation of, for example, P and Mn is thereby averted. The generation of surface flawing and cracking of the steel owing to O and Mn is thus prevented.

Title: Ghost eliminating device
Inventor: MURAKAMI HIRONORI
IPC: H03H15/00
Filed: 1987-02-03
Abstract: PURPOSE:To keep the output amplitude constant by using the result of calculation by a tap coefficient obtained for ghost elimination so as to apply output amplitude control. CONSTITUTION:A computing element 4 applies correlation operation between an input signal waveform and an error signal waveform between an output signal waveform fed back from an adder 6 and a reference signal waveform to detect ghost so as to decide tap coefficients C-M-CO-CN of multipliers T-M-TO-TN controlling the gain of each tape. The adder 8 takes the sum of outputs from each tap subject to gain adjustment by using the tap coefficients C-M-CO-CN. The tap coefficients C-M-CO-CN are corrected and decided so as to minimize the error signal waveform between the reference signal waveform and the input signal waveform. Then, the video signal subject to ghost elimination is applied from the adder 6 to the amplifier 7. The amplifier 7 uses the tap coefficients C-M-CO-CN for the calculation and is subject to gain control by a CPU 5 to make the video signal amplitude outputted from an output terminal 8 constant and a video signal whose ghost is eliminated and having a constant amplitude is obtained at the output terminal 8.

Title: Lubricator fitted with head tank
Inventor: NEGISHI TADANOBU
IPC: F16N29/02
Filed: 1982-02-17
Abstract: PURPOSE:To make the capacity of a head tank reducible ever so minimal, by adjusting the amount of lubricant to be fed to a lubricating part from the head tank in accordance with the speed of a rotary machine. CONSTITUTION:The speed of a rotary machine is detected by a tachometer 9 and since the opening of a control valve 8 is designed to be controlled by a signal from this tachometer 9, an oil quantity corresponding to the speed of the rotary machine is fed to a lubricating part from a head tank 5 in consequence. Therefore, the oil quantity required to be supplied at the head tank 5 for the duration ranging from the rotary machine's stopping signal to its complete stoppage is merely enough to be a time integral value of mechanical loss. As a result, the capacity of the head tank 5 can be extremely reduced.
